Undefined Questions


#1

This might not make any sense but why are you only able to make an undefined variable using let, and not const?


#2

good question actually.

constant variables can’t be changed:

const x = 'initial value'
x = 'attempting to re-assign, will given an error'

so declaring variables with const and giving it no value would be pointless, we can’t change constant variable later. let variable can be re-assigned, which is possible to give them no value in the beginning.

I see. Thanks for answering my odd question!
